MLB.com’s Scott Merkin wrote last month that there was a “better-than-average” chance of left-hander Carlos Rodon — who was selected third overall in this year’s draft — joining the White Sox as a September callup. But it’s not going to happen.

Rodon was a star in college at North Carolina State and has skyrocketed through Chicago’s farm system, posting a 2.92 ERA and 38 strikeouts in 24 2/3 innings between the rookie-level Arizona League and Triple-A Charlotte. He got an above-slot $6.6 million signing bonus from the White Sox in July.

Buchholz, 33, was acquired by the Phillies from the Red Sox in December 2016, but he made only two starts before an MRI revealed he had a partial tear of his right flexor pronator mass. He underwent surgery in April and missed the rest of the season.
